Does anyone know the differences between the (far more expensive) 2
part epoxy garage floor paints vs. the less expensive 1 parts(no
mixing)? I recently bought a Quikrete 2 part epoxy floor paint kit for
my garage. The kits are around $60, but you can't buy the paint alone!
I needed 3 more gallons and would have had to buy 3 more kits. SO, I
saw right NEXT to the Quikrete kit, a product also made by Quikrete
called "seal-krete" for garage floors and other concrete surfaces. It
claims to be "one part epoxy" and makes very similar claims about
durability, heat resistance, etc. This paint sells for $25/gallon. So,
I bought the closest color match and have almost finished the floor. I
painted over the remaining "good" epoxy paint after it had cured for
about 12 hours (hope the new stuff sticks OK).

Admittedly, it seems the two part was thicker, glossier, etc.
Interestingly enough it also didn't cover nearly as much space per
gallon as the cheaper paint did. I just wonder how the MFG can make
nearly the same claims about these two different types of paint. How
does the epoxy even work in a 1 part kit? I always thought epoxy
required "activation" as in the 2 part kits. Any ideas/experience on
this would be appreciated. Thank you!
